Which compound would be expected to have the lowest pK_a? A)water B)acetic acid C)ethane D)acetylene E)ethanol

Question

Quizplus · Accepted Answer

Acetic acid is expected to have the lowest pKa value among the options given because it is an acid and can donate a proton (H+), unlike the other compounds listed, which are not acids in the traditional sense. The pKa value is a measure of the strength of an acid, with lower values indicating stronger acids. Ethane, acetylene, and ethanol are not acids, and water, while it can act as an acid, is much weaker than acetic acid.
